Abstract

A strap lock has a flexible strap having a leading end and a trailing end. A locking device includes a first strap engagement portion that is capable of holding one part of the strap in position with respect to the locking device in a lock position thereof, and releasing the one part of the flexible strap in a release position. A second strap engagement portion engages another part of the flexible strap. A lock is capable of locking the first strap engagement portion in the lock position. The strap is preferably woven from strands of metal and high strength polymer.

15. The strap lock of claim 14, wherein said pivot member comprises engagement holes and said lock comprises respective engagement pins for engagement with said engagement holes.

16. The strap lock of claim 13, wherein said pivot member, when said holding member is in said locked position, is positioned to prevent said post from escaping said post chamber.

17. A strap lock, comprising:

a flexible strap having a leading end and a trailing end; and

a lock device comprising a first strap engagement portion capable of holding one part of said strap in position with respect to said lock device in a locked position thereof and releasing the one part of said flexible strap in a release position thereof, a second strap engagement portion for engaging another part of said flexible strap, and a lock capable of locking said first strap engagement portion in the locked position;

wherein said first strap engagement portion comprises a strap receiving channel for slidably receiving said leading end of said strap and a strap holding member positioned along said strap receiving channel; and

wherein said strap holding member is movably mounted with a pivot member and said pivot member is pivotally mounted with respect to said lock device to move said holding member between said release position and said locked position.

18. The strap lock of claim 17, wherein said lock is operable to lock said pivot member when said pivot member moves said holding member to said locked position.

19. The strap lock of claim 18, wherein said pivot member comprises engagement holes and said lock comprises respective engagement pins for engagement with said engagement holes.

20. The strap lock of claim 17, wherein said strap holding member comprises a knurled member.

21. A strap for a strap lock, comprising a flexible strap having a leading end and a trailing end and woven from strands of metal and strands of a high strength polymer, wherein said strap has a post on said trailing end for receipt in a post chamber of a strap lock.

22. A strap lock body for a strap lock, comprising:

a first strap engagement portion capable of holding one part of a strap in position with respect to said first strap engagement portion in a locked position thereof and releasing the one part of the flexible strap in a release position thereof;

a second strap engagement portion connected to said first strap engagement portion for releasably engaging another part of the flexible strap so that the other part of the flexible strap can be engaged and released; and

a lock capable of locking said first strap engagement portion in the locked position.

23. The strap lock body of claim 22, wherein said first strap engagement portion comprises a strap receiving channel for slidably receiving said leading end of said strap and a strap holding member positioned along said strap receiving channel.

24. The strap lock body of claim 23, wherein said strap holding member is movably mounted with a pivot member and said pivot member is pivotally mounted with respect to said lock to move said holding member between said release position and said locked position.

25. The strap lock body of claim 24, wherein said lock is operable to lock said pivot member when said pivot member moves said holding member to said locked position.
